public static bool SetSelection (Profiling.IProfilerFrameTimeViewSampleSelectionController controller, string markerNameOrMarkerNamePath, long frameIndex, string threadGroupName, string threadName, ulong threadId);

パラメーター

controller The controller object of the Profiler module whose selection you want to set. When the value is null, Unity throws a NullArgumentException.
markerNameOrMarkerNamePath The name of the sample to be selected, or the names of all samples in the sample stack. Separate each name with a /, ending on the sample that should be selected. Do not add a trailing /. If Unity cannot find a sample that matches this name or sample stack, it does not set a selection and this method returns false. When this value is null or an empty string, Unity throws an ArgumentException.
frameIndex The 0 based frame index. This value defaults to -1 which means the selection is set on the currently shown frame. Note that the Profiler Window UI shows the frame index as n+1. When this value is outside of the range described by ProfilerWindow.firstAvailableFrameIndex and ProfilerWindow.lastAvailableFrameIndex, or not -1, Unity throws an ArgumentOutOfRangeException.
threadGroupName The name of the thread group. The parameter defaults to an empty string. Null or an empty string signify that the thread isn't part of a thread group. "Job", "Loading" and "Scripting Threads" are examples of such thread group names.
threadName The Name of the thread, e.g. "Main Thread", "Render Thread" or "Worker 0". This parameter defaults to "Main Thread". When this value is null or an empty string, Unity throws an ArgumentException.
threadId The ID of the thread. When the default value of FrameDataView.invalidThreadId is passed, Unity searches for the sample in the first thread matching the provided threadGroupName and threadName. Specify this threadId if there are multiple threads with the same name. Use a RawFrameDataView.threadId or HierarchyFrameDataView.threadId to retrieve the ID to a specific thread, if you need it to be specific.

戻り値

bool Returns true if the selection was successfully set, false if it was rejected because no fitting sample could be found.

説明

Set the current selection in a frame time sample based Profiler Module, such as the CPU Usage module and the GPU Usage Profiler module.

Use these extension methods to IProfilerFrameTimeViewSampleSelectionController to search for a sample according to its name or Profiler Marker Id, the frame and the thread it occurred in and optionally a sample stack within which it should be found. If a sample matching these criteria is found, this method will return true and you can get the details on the found and set selection via IProfilerFrameTimeViewSampleSelectionController.selection.

When no frame data is available in the Profiler Window, Unity throws an Exception. You can check that ProfilerWindow.firstAvailableFrameIndex is greater or equal to 0 to validate that frame data is available.

When the specified thread can not be found, Unity throws an ArgumentException.

If you know the rawSampleIndex to the sample you want to select, you can use IProfilerFrameTimeViewSampleSelectionController.SetSelection directly to set the selection. See Also: IProfilerFrameTimeViewSampleSelectionController.SetSelection and IProfilerFrameTimeViewSampleSelectionController.ClearSelection.

パラメーター

controller The controller object of the Profiler module whose selection you want to set. When the value is null, Unity throws a NullArgumentException.
frameIndex The 0 based frame index. Note that the Profiler Window UI shows the frame index as n+1. When this value is outside of the range described by ProfilerWindow.firstAvailableFrameIndex and ProfilerWindow.lastAvailableFrameIndex, or smaller than 0, Unity throws an ArgumentOutOfRangeException.
threadGroupName The name of the thread group. Null or an empty string signify that the thread isn't part of a thread group. "Job", "Loading" and "Scripting Threads" are examples of such thread group names.
threadName The Name of the thread, e.g. "Main Thread", "Render Thread" or "Worker 0". When this value is null or an empty string, Unity throws an ArgumentException.
sampleName The name of the sample to select. If Unity cannot find a sample that matches this name, it does not set a selection and this method returns false. When this value is null or an empty string, Unity throws an ArgumentNullException or ArgumentException respectively.
markerNamePath The names of all samples in the sample stack, each separated by a /, that define the base path for the search. Similar to a file folder structure, this base path defines where Unity looks for a sample which matches the sampleName. The searched sampleName can be the last item in that marker path or any child sample of it. Do not add a trailing /. If no sample can be found matching this sample stack path and the sampleName, no selection is set and this method returns false. This defaults to null which means no requirement is set on the sample's sample stack and the first sample fitting the sampleName is selected.
threadId The ID of the thread. When the default value of FrameDataView.invalidThreadId is passed, Unity searches for the sample in the first thread matching the provided threadGroupName and threadName. Specify this threadId if there are multiple threads with the same name. Use a RawFrameDataView.threadId or HierarchyFrameDataView.threadId to retrieve the ID to a specific thread, if you need it to be specific.
sampleMarkerId Use HierarchyFrameDataView or RawFrameDataView to get the Marker Ids. When no sample can be found matching this sample stack path and the sampleMarkerId, no selection is set and this method returns false.
markerIdPath A list of Profiler marker IDs for all samples in the sample stack, that define the base path for the search. Similar to a file folder structure, this base path defines where Unity looks for a sample which matches the sampleMarkerId. The searched sampleMarkerId can be the last item in that marker path or any child sample of it. If no sample can be found matching this sample stack path and the sampleMarkerId, no selection is set and this method returns false. This defaults to null which means no requirement is set on the sample's sample stack and the first sample fitting the sampleMarkerId is selected.

戻り値

bool Returns true if the selection was successfully set, false if it was rejected because no fitting sample could be found.
